For a $5 dollar upgrade charge, I can make the heatsinks threaded for AixiZ threads, and have a press fit design for the diode. (copper or aluminum)

In this case, the heatsink will be a little shorter. (length of an AixiZ module)

But it would still be a better design I believe for better heatsinking. It's basically just a large module that fits the host...

I will still offer both styles, because the normal design (for using an AixiZ module), still may be desirable. Especially if you will be using an EzFocus adapter. Being able to move the module position aids in getting the perfect position of the EzFocus adapter in relation the the host. This allows the use of different lenses using the EzFocus adapter. (being able to adjust module position)

I do not, but copper is fairly soft, and it would be really easy to use a small tipped punch, and tap a couple of divots near the edge of the hole that the diode presses into, and this would make the fit tighter. So that you could press the diode in tighter...

Jay , How much for one of those heatsinks? I'd like to upgrade my kit to one of those.

I got the package today. The red is finished. It peaked at 231mW and settled around 225. I'll post some pictures in the topic I create specifically for my pictures/videos once I have the 445 done. I'm going to be gone a few days and hope to have the 445 diodes waiting for me.

I think I'm going to have to build use another one of these kits for the green module I have. The only problem is the driver was removed. The module came from the leadlight that dr lava modded.

sem020106, at 850mA's for your 445 build, you will want to make sure you have the highest quality 18650 battery to handle the current draw.

I recommend AW brand. You can get them at lighthound.com

If anybody is not yet aware of this option (sem020106's build), here's the information. (noted in the first post now)

445 Build:

The 18650 host (and/or DIY Green host) can fit a larger heatsink if desired, by drilling out the top of the pill and mounting the driver inside the pill like with my Pocket Mini kits. Then the heatsink can be longer yet.

In the original design, I just didn't think it was really necessary to have the heatsink larger.

But if your planning on a 445 build with an AixiZ 405 glass lens, then you will want this option...

Because since the lens sticks out farther than other lenses, you can have room inside to position your module farther back into the heatsink to get your focus ring near flush with the heatsink for a better look. (and especially if you plan on using my EzFocus adapter)

Let me know when you order, and I can set it up that way for an extra $10 bucks... (but it will not have the press fit design option in this case)

I just realized that I hadn't posted back here after my kit arrived and I finished the build.

Everything went smoothly and the laser works as expected. jayrob set mine at 400mA with the MicroBoost but I've no idea what the power output actually is. I can say that, when focused, the beam causes EVERYTHING to start smoking instantly and catch fire a split second later.

I'd say I've got about 30 or 40 minutes of run time on it so far, about 15-20 seconds at a time, maybe one or two runs up to a minute.

I ordered a nice microphone stand from Amazon to hold the pointer steady so that I can aim it at something further away than a foot and still get it focused to a point.

There's really only one complaint that I have about the entire thing: the spring in the battery compartment was WAY too long.

I'm not sure why this isn't noted in the directions that came with it (particularly considering that I've got the same battery pictured in the guide) but there is no way that any 18650 cell would fit in mine without trimming the spring because the bottom wouldn't even screw on all the way until I cut it back by about 1cm. This particular problem also causes the driver & wires start to twist if you haven't trimmed it far enough. Without attention, at some point they'll pop loose and you'd have to resolder them (assuming it doesn't short and fry the diode or driver). It's not a gigantic issue since the 18650 has a massive run time, but for someone who pays less attention than I do, they might end up killing it pretty quickly.

But I don't understand, how can i use it if there is no surface for the + of the battery to touch? I mean, the spring is ok( for the - of the battery) but what about the + ? I'll be using a flexdrive and this will be a 445 nm build. Can you give me a hand ?
